Title: Air conditioning by admixture of fresh warm or cool air - annular nozzle mixes fresh and stale air at nozzle outlet, eliminates draughts
Inventor: SCHEEL ARNOLD DIPL ING
IPC: F24F13/26
Filed: 1974-10-30
Abstract: When the air in a room, or near a workbench, is to be kept warm, cool or moist, by admixture with fresh hot or cold air introduced through a nozzle, the mixing must take place close to the nozzle if uncomfortable draughts are to be avoided. This is done by using a nozzle in which the freshly warmed air is blown through a conical annulus (6) surrounding a cylindrical tube (2). The warm air sucks air from the general circulation through the central tube and mixes with it at the common outlet. The annulus narrows somewhat between its hot air inlet and outlet, accelerating the current; and it preferably extends a little beyond the end of the central cylindrical tube.

Patent DE-2512859-A1 (DE)
Title: Injector for spraying water into engine cylinder - is used to improve fuel efficiency and lower engine temperature
Inventor: MUELLER FRANZ
IPC: F02B3/06
Filed: 1975-03-24
Abstract: Injector for injecting coolant liquid such as water into the combustion chamber of internal combustion engines. This injection system is used for saving fuel and for increasing power. The coolant liquid injected is evaporated and the supply of this liquid is regulated in relation to the temperature of the cylinder walls and fuel suppled to ensure complete coolant evaporation. The coolant is injected after ignition so that the combustion process is not affected. The temperature in the combustion chamber is lowered and the vapour generated compensates largely for the compressed fluid volume reduction caused by cooling. Lower heat losses to the combustion chamber walls result and on using water as coolant the high specific heat content of exhaust gas ensures that the exhausted mixture expands to a lesser extent than conventional exhaust gas.
Patent DE-2516228-A1 (DE)
Title: Pressure conveyor vessel for bulk material - has two valves regulating duration of lower air current injections and intervening intervals
Inventor: ZINNAECKER HANS-DIETER

Filed: 1975-04-14
Abstract: The pressure conveyor vessel is for the pneumatic transport of material in bulk. The duration lof injection and the intervening intervals of the lower air current are regulated by two pneumatic valves of similar construction, thus allowing intermittent plugs of air to be produced, or a continuous flow. A number of augers lof small diameter in relation to that of the vessel and of different lengths can be used, interchangeably mounted in the vessel and extending into the outlet, their speed also being variable. The upper and lower air currents can be supplied by a large number of small compressors, thus allowing a wide difference in pressure and rate of flow between the two currents.

Title: Foil seam resistance welding zinc coated steel sheets - using porous foils made from powdered metals
Inventor: GUENTHER KURT DIPL ING
IPC: B23K11/16
Filed: 1975-05-13
Abstract: The foil is made by powder metallurgy using raw matls. and prodn. methods related to the chemical compsn. reqd., the distribution of the alloying elements, and the open residual porosity. The foil pref. has a residual porosity up to 25% and may consist of >=2 layers, one being Fe and the other a matl. with higher corrosion resistance. When resistance welding steel sheet which is Zn coated, mild steel foil is placed on both sides of the joint to reduce heat losses and keep Zn off the electrodes, but Zn flows away from the joint, thus impairing its corrosion-resistance. Stainless steel foil can be used or the joint coated with lacquer, but both methods involve increased costs. Inexpensive, corrosion-resistant joints are obtd. without using stainless steel.
